Over the past couple of years, we've seen Zac Efron, Corbin Bleu, Ashley Tisdale and Vanessa Hudgens go from teen idol wannabes to full-fledged teen dreams. In this installment of the "High School Musical" franchise, their characters — Troy Bolton, Chad Danforth, Sharpay Evans and Gabriella Montez — are graduating, saying farewell and heading off to college. But what senior year is complete without some good old-fashioned senior superlatives?

So we asked the cast, old and new, to weigh in on the students of East High's Class of 2008.

Most Likely to Laugh in the Middle of a Take

Zac Efron: Chris Warren Jr. [who plays Zeke in the series]. We don't have to think about it.

Vanessa Hudgens: A lot of us. When we get into this giggly mode, we can't help ourselves.

Matt Prokop: Chris Warren.

Justin Martin: His laugh is incredible. He has this high-pitched [laugh].

Jemma McKenzie-Brown: Yeah, and they kept it! They kept it in the film.

Prokop: And it was just so funny and so random that they just had to keep it in the movie.

Most Likely to Win an Oscar

Corbin Bleu: Zac Efron.

Efron: I was going to say Lucas [Grabeel, who plays Sharpay's brother Ryan]. Corbin, for sure. He's right next to me, so ...

Ashley Tisdale: For me, Lucas. He's so good, and he's so great to play his character. He's going to shock a lot of people.

Prokop: Lucas.

McKenzie-Brown: Such a multitalented person. He can do everything. When you think you've seen everything, he'll pull out a guitar.

Most Likely to Win a Dance-Off

Efron: Corbin. ... He just consistently wins dance-offs.

Hudgens: Corbin. He's very versatile.

McKenzie-Brown: He can do everything — every single style of dance, Corbin has been into. He just bought a set of flamenco shoes as well, so now he can go flamenco dancing. He bought them in Spain.

Most Likely to Have Lil Wayne Make a Guest Appearance on Their Album

Bleu: Vanessa.

Efron: Yeah. Vanessa, maybe — that'd be awesome.

Tisdale: [To Hudgens] I thought you!

Hudgens: Me or Zac.

Martin: Justin Martin! I'm actually working on an album right now, so that'd be amazing.
